How it works
Anti-snipe
Why the first buyers pay more, and exactly how much more.
Bots watch for new launches and buy in the first block, ahead of everyone who found the coin by reading about it. The answer here is not a whitelist — the programs have no such thing — but a fee that starts punishing and decays fast.
Solana
The fee opens at 5× the launchpad's rate and decays linearly to it over 5 minutes, in 30 steps. On a 1% launchpad, the first buyers pay 5% and everyone after the fifth minute pays 1%.
EVM
Sharper and shorter: the fee opens at the contract's 80% cap and decays to the token's own rate over 5 seconds. A launch-block sniper pays nearly everything; a buyer six seconds later pays the normal fee.
The decay initializer exists only on the Base family. On other EVM chains launches take the default path at the flat fee, and the wizard says so on the chain you pick.
It applies to everyone
Including the creator. The fee is pool-wide with no exemption list, so a creator buying their own coin in the first seconds pays the elevated rate like any bot. There is no field to exempt a team wallet, because there is no mechanism behind it and faking one would be worse than saying so.
Who counts as a sniper
The token page reports snipers as wallets whose first trade landed inside that window — people who demonstrably paid the elevated fee, rather than a guess at intent. Their remaining share is counted from indexed trades, so tokens moved by plain transfer are not tracked.
